ALGEBRA-TOPOLOGY SEMINAR

"Bredon-Illman Cohomology with Local Coefficients II"

By

TURGUT ÖNDER

(METU)

Abstract: This will be the second of the
two introductory talks on Bredon-Ilman Cohomology with local coefficients. This is a cohomology  associated to
each G-space X, where G is topological group, with a suitable local coefficient
system on X, and it satisfies all the equivariant Eilenberg-Steenrod axioms. The main motivation to study
this cohomology is the related equivariant
obstruction theory for equivariant sections of a G-fibraton over a G-CW complex when G is a compact Lie group.

Tea and cookies will be served after the
seminar.
